Konqueror ignores image file association

Bonjour,

An issue occurs after using Konqueror as the file manager for years.
It has always opened image files in Gwenview. It now ignores it and keep opening the image file in its embedded simple viewer.

When trying the right-click “Open With” menu on the file and “Set as default app” it opens in Gwenview … once. Double-clicking the file then doesn’t call Gwenview anymore but Konqueror embedded viewer again.
Strangely the File Associations config is right, remembering my choice, with Gwenview as only application.

Same occurs when trying

  • to open JPG or PNG files
  • to set another separate viewer (Firefox) as default
  • within a new user session.
    But :
  • application switch works when trying to change video file association
  • Dolphin file manager respects the file association and opens images in Gwenview as expected.

~/.config/mimeapps.list lists

[Added Associations]
image/jpeg=org.kde.gwenview.desktop;
image/jpg=org.kde.gwenview.desktop;

[Default Applications]

image/jpeg=org.kde.gwenview.desktop;
image/jpg=org.kde.gwenview.desktop;

(image/jpg has been added by me as a try but I guess it has no effect)

Konqueror version is 25.12.3.
KDE is 6.6.4.

Is it a reproducible issue ?
Should I check the config elsewhere ?

Thanks for your help.
